Instructions

1. Power Supply:

   • Connect the VCC pin to a stable 4.5V to 5.5V power supply.
   • Connect the GND pin to the ground.

2. Reference Voltage:

   • Connect the VREF pin to an external reference voltage source within the range of 2.5V to 5.5V.

3. SPI Interface:

   • Connect the SCLK (Serial Clock) pin to the clock signal from the microcontroller.
   • Connect the SDI (Serial Data In) pin to the data output of the microcontroller.
   • Connect the CS (Chip Select) pin to the chip select signal from the microcontroller.

4. Output Configuration:

   • The DAC outputs (OUTA and OUTB) can be connected to the load or further buffering stages as required.

5. Initialization:

   • Ensure that the CS pin is held high when not in use to keep the device in a high-impedance state.
   • To write to the DAC, bring the CS pin low, send the appropriate command and data via the SPI interface, and then bring the CS pin high again.

6. Shutdown Mode:

   • To enter shutdown mode, set the appropriate bit in the control register to reduce power consumption to 1 μA.

7. Calibration:

   • For optimal performance, calibrate the DAC using the provided calibration registers to correct for any non-linearity errors.

8. Handling:

   • Handle the device with care to avoid static damage. Use proper ESD protection when handling the component.

9. Storage:

   • Store the device in a dry, cool place to prevent moisture damage. Follow the storage recommendations provided by the manufacturer.
